Water-damage-resistant and storable cold patch asphalt mixture and preparation method thereof
The invention relates to the technical field of road asphalt materials, and discloses a water-damage-resistant and storable cold patch asphalt mixture and a preparation method thereof. The cold patch asphalt mixture comprises the following components in parts by weight: 100 parts of matrix asphalt, 1.5-9.5 parts of a modifier, 15-40 parts of a diluent and 1950-2700 parts of aggregate, wherein the modifier comprises SEBS (Styrene-Ethylene-Butylene-Styrene); and the use amount of the matrix asphalt and the modifier is 4.0-5.2% of the mass of the aggregate. By optimizing the components of the cold patch asphalt mixture, adding the specific modifier and controlling the mass of the modifier and the matrix asphalt and the use amount of the relative aggregate, the residual stability and the freeze-thaw splitting strength of the cold patch asphalt mixture are improved compared with those of an unmodified cold patch asphalt mixture; and after being stored for a period of time, the product can be taken at any time, and subsequent procedures and working performance are not affected, so that the water damage resistance and the storage stability are enhanced.
本发明涉及道路沥青材料技术领域，公开了一种抗水损害和耐存储的冷补沥青混合料及其制备方法。本发明的冷补沥青混合料包括以下重量份各组分：100份基质沥青、1.5～9.5份改性剂、15～40份稀释剂、1950～2700份集料，改性剂包括SEBS；基质沥青和改性剂的用量为集料质量的4.0～5.2％。本发明通过优化冷补沥青混合料组分，加入特定改性剂，并控制改性剂与基质沥青的质量和相对集料的用量，使冷补沥青混合料的残留稳定度及冻融劈裂强度比较未改性冷补沥青混合料得到提升，且可以在储存一段时间后能做到随用随取，并且后续工序和工作性能不会受到影响，因此抗水损害能力和储存稳定性能得到增强。
